6. Check the Aftertreatment System for Oil
A. Remove excess oil from piping with a clean cloth.
B. Remove the Clean Emissions Module (CEM). Refer to Disassembly and Assembly, "Clean Emissions Module - Remove and Install".
C. Support the CEM over a suitable container with the exhaust inlet downwards. Leave the CEM to drain for 8 hours.
D. Check the quantity of drained oil in the container.
CEM
Result The volume of drained oil is greater than 1.0 L (1.06 qt).
Repair: Install a replacement CEM. Refer to Disassembly and Assembly, "Clean Emissions Module - Remove and Install".
Return the unit to service.
Result The volume of drained oil is less than 1.0 L (1.06 qt).
Proceed to Test Step 7.
7. Recover the Aftertreatment System
A. Clean any remaining oil from the piping and the CEM inlet with a clean cloth.
B. Install the Clean Emissions Module (CEM). Refer to Disassembly and Assembly, "Clean Emissions Module - Remove and Install".
C. Run the engine at high idle with no load for a minimum of 20 minutes.
D. Use the electronic service tool to perform the "Aftertreatment Recovery Procedure". While the procedure is progressing, check for smoke from the exhaust. Some smoke will be evident during the procedure. The smoke must dissipate before the procedure is completed.
CEM
Result: The "Aftertreatment Recovery Procedure" completes with a soot load of less than 80% and no smoke from the exhaust.
Return the unit to service.
Result The "Aftertreatment Recovery Procedure" completes with a soot load of more than 80% or smoke from the exhaust.
